I have not hooked it up via ethernet but so far it is working just fine wireless. I do have a very fast dual band router however.
I love the fact I can now stream the OTA content I receive from my outside HDTV antenna to all my devices and Smart TV.
The guide and DVR function is outstanding. I am using the trial version now, but will probably buy the lifetime subscription and be done with it.
I will try the streaming from outside the house via cell phone or other wifi after I configure the router accordingly.
Bottom line, works great, easy setup, great with guide and DVR. Worth my money and I cut the cable TV cord for good! There is tons of good OTA content with more all tje time. The Tablo aggregates it all and provides a great guide and can stream on all devices in the house (only 2 at a time however).
